Who was studied up to 72,390 Japanese ancestry women, up to 85,894 Japanese ancestry men; replicated in up to 10,048 Japanese ancestry women, up to 5,098 Japanese ancestry men, up to 181,999 European ancestry women, up to 140,155 European ancestry controls.
The effect
Each copy of the T allele shifted the measure 0.017 higher (95% confidence interval 0.013-0.021); p = 2 × 10−12.
How common The T allele had a frequency of about 38% in the people studied.
Where it sits Chromosome 3, band 3p21.1 — in an intron of ITIH3.
What each result means
C/CNo copy of the version the research linked to Body mass index. This is the starting point the study compared everyone against.
C/TOne copy of the version the research linked to Body mass index. That is a smaller link than two copies.
T/TTwo copies of the version the research linked to Body mass index. That is the strongest link of the three results. A link in a study is not a diagnosis.
rs2240920 is a single position in the genome, in or near the ITIH3 gene. Published research associates it with body mass index. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
What conditions is rs2240920 linked to?
On MyGeneLog this position is linked to Childhood Body Mass Index. The research behind each link, and its sources, are set out on that condition page.
Does having rs2240920 mean I will get this?
No. Common variants like this one move a probability slightly and, on their own, rarely decide anything about one person. Nothing on this page is a diagnosis, and health decisions should be made with a clinician who can see your whole picture.
Where does the information about rs2240920 come from?
GWAS Catalog, Nature genetics 2017, PMID:28892062. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
